The present case has been published in the International Journal of Surgery Case Reports. The Masquelet technique is a well-known and efficient procedure for lower limb soft tissue reconstruction after severe osteomyelitis requiring bone excision. However, this technique is rarely used in the hand.The patient was a 38-year-old man. We used this technique to reconstruct a proximal interphalangeal (PIP) joint osteochondral defect after osteomyelitis caused by clenched-fist human bite injury. The pathogen was Prevotella intermedia, which is an anaerobic pathogenic bacterium involved in periodontal infections and is a black-pigmented periodontal pathogen. Following completion of the Masquelet method, the bone remodeled at an angle at the PIP joint. The angled joint resulting from this technique created a relatively normal permanently bent PIP joint.Lessons to be learned:-- Prevotella intermedia is known as Bacteroides melaninogenicus subsp. intermedius. When the infection site is black-pigmented, this pathogen is highly suspected. - The Masquelet technique is rarely used in the hand, and when used, it has been in a straight fashion in the hand. - The authors were able to reconstruct a more anatomical, bent PIP joint, and the fixed angle of the PIP joint at 40 degrees of flexion using Masquelet technique.Read in detail here: https://pxmd.co/m81QN
